摘要： A wearable image display system comprises a headpiece, a light engine, and an optical component. The light engine is mounted on the headpiece and configured to generate beams, each of the beams being substantially collimated so that the beams form a virtual image. The optical component located to project an image onto an eye of a wearer and comprising an incoupling structure and an exit structure. The beams are directed from an exit aperture of the light engine to the in-coupling structure of the optical component. The exit structure is arranged to guide the beams onto the eye. The optical component is located between light engine and the eye. The optical component is angled relative to the light engine such that any outwardly reflected versions of the beams propagate clear of the exit aperture.

摘要： A wearable image display system comprises a headpiece, a first and a second light engine, and a first and a second optical component. The first and second light engines generate a first and a second set of beams respectively, each beam substantially collimated so that the first and second set form a first and a second virtual image respectively. Each optical component is located to project an image onto a first and a second eye of a wearer respectively. The first and second sets of beams are directed to incoupling structures of the first and second optical components respectively. Exit structures of the first and second optical components guide the first and second sets of beams onto the first and second eyes respectively. The optical components are located between the light engines and the eyes. Both of the light engines are mounted to a central portion of the headpiece.

摘要： An apparatus for use in replicating an image associated with an input-pupil to an output-pupil includes a planar optical waveguide including a bulk-substrate, and also including an input-coupler, an intermediate-component and an output-coupler. The input-coupler couples light corresponding to the image into the bulk-substrate and towards the intermediate-component. The intermediate-component performs horizontal or vertical pupil expansion and directs the light corresponding to the image towards the output-coupler. The output-coupler performs the other one of horizontal or vertical pupil expansion and couples light corresponding to the image, which travels from the input-coupler to the output-coupler, out of the waveguide. The apparatus further includes an adjacent planar optical component to provide a more uniform intensity distribution compared to if the adjacent planar optical component were absent.

摘要： The technology provides decoupling an aspheric optical element from a birdbath optical element in a near-eye display (NED) device. One or more aspheric lens are used with a spherical birdbath reflective mirror in a projection light engine of a NED device. A projection light engine provides image light (or other information), by way of the spherical birdbath reflective mirror and at least one aspheric lens, to a near-eye display of the NED device. The spherical birdbath reflective mirror collimates and reflects the image light to an exit pupil external to the projection light engine. Decoupling the aspheric optical element from the spherical birdbath reflective mirror may enable high modulation transfer function (MTF) and improved manufacturability of the projection light engine. The NED device having aspheric optical elements decoupled from a birdbath optical element may be positioned by a support structure in a head-mounted display (HMD) or head-up display (HUD).

摘要： Introduced here is a display device that comprises a light emitter and a diffractive optical element (DOE) that is optically coupled to receive light from the light emitter and to convey the light along an optical path. The DOE may have an input surface and an output surface parallel to the input surface, where the input surface and the output surface each have a central region and a peripheral region. The DOE further may have optical characteristics such that light exiting the DOE in the peripheral region of the output surface has greater brightness than light exiting the DOE in the central region of the output surface.

摘要： A head-mounted display device comprises a rendering engine configured to generate a hologram representative of a three-dimensional object. The hologram includes depth information that causes the three-dimensional object to be rendered with a focus that is determined by the depth information. The device also includes a spatial light modulator that modulates light from a light source as indicated by the hologram. A switchable hologram comprises multiple stacked switchable gratings. Each of the stacked switchable gratings is associated with one or more resulting exit pupil locations on a viewing surface. The system also comprises an eye tracker configured to map a viewing direction of a user's eye to a viewing location on the viewing surface. A processor is configured to activate a particular switchable grating within the switchable transmission hologram that is associated with an exit pupil location that aligns with the viewing location.
